SPRAYING OB SPBINKLING NOZZLE.

Specification of Letters Patent.

Patented se t. 29, 1914..

Application filed October 13, 1913. Serial No. 794,975.

To all whom it may concern:

Be it known that I, JOHN L. SARGENT, a citizen of the United States,residing at Indianola, in the county of Redwillow and State of Nebraska,have invented a new and useful Spraying or Sprinklin Nozzle, of whichthe following is a specification.

The present invention appertains to. a spraying or sprinkling nozzle,and aims to provide a novel and improved device of that character.

The object of the present invention is to provide a nozzle of thecharacter indicated, embodying unique means for controlling thedischarge of the water or fluid therefrom according to its volume andpressure.

Another object of the present invention is to provide in combinationwith the "nozzle tube or pipe, a valve seatable on the free end thereof,and a yieldable governor connected to the valve for controlling themovement thereof away from the end of the nozzle tube, according to thevolume and pressure of the fluid.

Among its other objects, the present invention contemplates theprovision of a device of the nature indicated, which will becomparatively simple, durable, and inexpensive in construction, as wellas simple and efficient in its use.

lVith the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention.

The invention has been illustrated in its preferred embodiment in theaccompanying drawing, wherein Figure 1 is a longitudinal central sectionof the improved nozzle. Figs. 2 and 3 are cross sections taken on thelines 2-2 and 33 of Fig. 1, respectively.

In carrying out the present invention, there is provided a tubularnozzle body or casing 1, which has an elbow 2 threaded or otherwisesecured upon the receiving end of the nozzle tube 1, in order that asupply pipe or hose 3 may be engaged within the free arm of the elbow 2to supply water or fluid to the nozzle. The nozzle tube 1 and its elbow2 may be mounted upon any suitable base or supporting structure,according to the use to which the device is piit. The nozzle tube 1 ispreferably circular in cross sectiofi, although it may be of othercontours as we A conical valve 4 is arranged to seat against the outeror free end of the nozzle tube 1, the conicalvalve 4 being inverted, andpreferably being of a diameter slightly greater than the diameter of thenozzle tube 1. The valve 4 is provided with a tubular stem 5 projectingfrom its apex axially into the nozzle tube 1, the stem 5 of the valvebeing slidable through a suitable spider guide .6 secured within thenozzle tube 1 adjoining its free end or mouth. 'A valve rod 7 is passedloosely through the valve 4 and its stem 5, and has a nut or stop 8threaded upon its outer end to seat against the base or face of thevalve 4, the inner end of the rod or plunger 7 being passed slidablythrough a spider guide 9 secured within the nozzle tube 1 intermediateits ends.

In order to control the opening movement of the valve 4, a screw or rod10 is passed slidably through the elbow 2 in axial alinement with thenozzle tube 1, and a nut 11 is threaded upon the exposed or free end ofthe screw 10 to seat against the elbow 2. A coiled wire contractile orretractile spring 12 is terminally connected to the adjacent ends of therods 7 and 10 so as to yieldingly seat the valve 4: against the end ofthe nozzle tube. The tension of the spring 12 may be regulated byadjusting the screw 10 through the medium of the nut 11, as will beapparent. The stem 5 of the valve being guided by the spider (i, and therod 7 passing snugly through the valve and its stem, being guided by thespider 9, will properly constrain the valve 1 to move axially withrespect to the nozzle tube.

The present nozzle may be employed for divers purposes, such as forspraying or sprinkling water, or other liquids or fluids.

.lVhen the liquid or fluid is admitted into the nozzle under pressure,the pressure of the fluid will unseat the valve 4 against the resistanceof the spring 12, until the pressure of the fluid and the tension of thespring become balanced or equalized. The fluid will thus be dischargedover the rim of the valve 4, and the stream of the fluid will begoverned both by the pressure of the fluid, and the tension of thespring 12, in order that the greater the pressure of the fluid, thegreater the movement of the valve 4 from its seat or the end of thenozzle tube. It is evident that the spring 12 may be so tensioned, as toprevent the discharge of the fluid, until the same has a given orpredetermined pr'essure. The other advantages and capabilities of thepresent nozzle will beapparent to thoseversed in the art, andneed not beitemized at length, it being observed that the objects aimed at havebeen carried out satisfactorily.

Having described the invention, what is claimed as' new is 1. In anozzle, a nozzle tube, a valve seatable against the end thereof andhavin a tubular stem projecting into the nozzle tu e, a rod passingloosely through the valve and its stem, a stop carried by the outer endof the rod and seating against the valve, a contractile spring disposedwithin the tube and connected to the inner end of the said rod,

and guides secured within the nozzle tube and slidably receiving thevalve stem and the said rod.

2. In a nozzle, a nozzle tube, an elbow secured to one end thereof, avalve seatable against the other end of the nozzle tube and having atubular stem projecting axially thereinto, a rod passing loosely throughthe valve and its stem, a second rod passing slidably through the elbow,nuts threaded upon the remote ends of the rods and seating against thevalve and elbow, respectively, a contractile spring connecting theadjacent ends of said rods, and guides secured within the nozzle tubeand slidably receiving the valve stem and first mentioned rodrespectively.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.

JOHN L. SARGENT.
